Ruby-libjit
:include: VERSION
Copyright (C) 2009 Paul Brannan
Ruby-libjit is a wrapper for the libjit library. It provides basic
functionality for jit-compiling functions, including integrating those
functions as callable methods from within Ruby. Abstractions are also
provided so that jit code may be written in a ruby-like manner.
Please see the file COPYING for license information.
To install it:
gem install ruby-libjit
but you'll probably need to install libjit itself first (see below).
A simple example:
:include: sample/simple.rb
Looping structures and other abstractions are provided to make writing
jit code easier:
:include: sample/fib.rb
To build ruby-libjit, you will need to install libjit. If it is not
available pre-compiled for your platform, you may build the latest
release like this:
$ wget ftp://ftp.gnu.org/gnu/dotgnu/libjit/libjit-0.1.2.tar.gz
$ tar xvfz libjit-0.1.2.tar.gz
$ cd libjit-0.1.2
$ ./configure
$ make
$ sudo make install
